Hi,
To me nutrition is the most important, so what if you do compound
weight exercises but nutrition sucks.
Eat protein and when i tell you eat protein i dont mean your pri 1
chicken rice portion at the hawker centre.I mean for one meal eat
thrice of that amount(opt for breast meat).Also make good friends
with the economical rice uncle and buy 4 meats with rice.Eat fruits
and veges as well.Have 6 meals a day.2 in the morning, 2 in the
afternoon and 2 at night.One small meal and one heavy meal each for
different times.Heavy meal would be what i stated, for a light meal
you can drink 250ml of milk and eat peanut butter WHOLEMEAL
sandwich OR TUNA sandwich( 2-3 slices) and some fruit(bananas
recommanded).You better drink one litre of milk a day.
AND YOU BETTER EAT AND EAT AND EAT 
PLEASE DONT SHOW ME YOUR KINDERGARDEN FOOD PORTION AND ASK ME IF
ITS ENOUGH.Sorry a bit deranged here.Stress...
good luck 
and please dont eat all the rubbish food served at coffee shops
like char kway teow.
Only eat those crappy food if you are bulking or something, they
are good for bulking(if you are skinny) and after that you
cut.
BUT THEY ARE SH*T for maintaining muscle.
